Today, s Businesses can only survive if they can sdapt fast, and this means their IT systems have to adapt too. A challenge for identifying and codifying reengineering expertise is to capture Both aspects of a successful enterprise business architecture(EBA) and suitable description language, with the contexts in which it works. In connected with the state of the art in the field of Web Services architecture and EBA, we propose to exploit the concept of business process execution language(BPEL), one among of description language. In addition, we review current a issue and problem of EAI and Workflow, and outline the main ingredients of a BPEL and EBA for building flexible Web Service. This paper is exploratory study in associated with enterprise architecture(EA) and description language.

Although the Korean government is making great effort to prevent the redundancy in IT investment and efficiently allocate the IT budget, actual achievements are quite limited because of the variety of IT resources and different architecture description among organizations and projects. Thus, a standardized description model of the system architecture is strongly needed to identify the common resources and improve the efficiency of IT investment. Therefore, in this paper, we have developed the function-network matrix model which can be used as the basic template for a standard for architecture description of e-Government systems. The function-network matrix model integrates the function tiers and the network areas into a single unified framework, which enables the functionality of each component and the flow of information clearly visible. Moreover, we described the architectures of Korean e-government’s citizen service systems using our model, resulting in clear demonstration of the similarities and differences between different systems, and easy identification of the common resources. Using the architecture description model developed in this research, the consolidation of national IT resources can be promoted, and non-expert IT users can easily recognize the architecture of their systems. In addition, more efficient and systematic IT resource management can be achieved using our model.

Recently, component-based development (CBD) is rapidly spreading as a way of improving the reusability, productivity, and quality of software. For CBD to be effective in achieving such design objectives, the creation and integration of components must be based on a well-defined architecture that guides the correct composition and cooperation of application components. Software architecture must be described using an architecture description language (ADL) to ensure the correctness and preciseness of architecture models. In this paper, we propose the system architecture of an ADL tool set that can effectively support the use of CBD based on the domain architecture and we describe each component of the proposed system architecture. We also modify and redefine C2SADL that was developed to support the use of the description of C2 architectural style by UCI (University of California in Irvine) to facilitate the integration of separately described architecture models, and introduce the method of design and implementation of our ADL processor that partially implements the proposed ADL system architecture.

Software architecture is the high level model of a software system. It should be specified with ADLs (Architecture Description Languages) for its clarity and preciseness. Most ADLs such as C2SADL have not come into extensive use in industries since ADL users should learn a distinct notation specific to architecture, and ADLs do not address all stakes of the development process that is becoming diversified everyday. On the other hand, UML is a do facto standard general modeling language for software developments. UML provides a consistent notation and various supporting tools during the whole software development cycle. But, UML is a general modeling language and does not provide all concepts that are important to architecture description. UML should be extended in order to precisely model architecture. In this paper, we defined a C2 architecture modeling language as a UML2.0 profile. We applied the defined C2 architecture modeling language to the modeling of a restaurant reservation system.

Software architecture, which is the high level model of a software system, should be specified with ADLs (Architecture Description Languages) for its clarity and preciseness. Most of ADLs such as ACME, however, have not come into extensive use in industries since ADL users should learn a distinct notation specific to architecture. On the other hand, UML is a do facto standard general modeling language for software developments. UML provides a consistent notation and various supporting tools during the whole software development cycle. UML, being a general modeling language, does not provide all concepts that are important to architecture description. UML should be extended in order to precisely model architecture. A number of researches on architecture modeling based on WML have been progressed. Ail of them, however, are based on the UML1.x. UML2.0 embraces much more concepts that are important to architecture modeling than UML1.x. In this paper. we defined an architecture modeling language based on UML2.0. We defined Generic ADL by extending UML2.0 and applied the defined Generic ADL to a restaurant reservation system.

Recently a new IT planning effort, Enterprise Architecture (EA), is being carried out by a number of organizations. According to many previous studies, this EA effort intrinsically differs from information systems planning (ISP). In practice, however, it is often performed just like ISP, pursuing identical objectives with just a few more modeling methods. It might lead to a misunderstanding that EA is no different from ISP. In an effort to clarify the difference, we investigate how these two planning efforts differ one from another in richness of architectural description. 19 RFP(request for proposal)s were empirically analyzed to see the difference between EA and ISP in terms of the richness of architectural description.

Systems architecture of information models for construction industry is introduced. The architecture ful fills international standards, such as ISO 10303(STEP) and IAI IFC, etc. It is defined in web service description language(WSDL) and ISO 10303-11(EXPRESS) language. A standard platform for this standard architecture is also developed. This platform has several tools which can transform EXPRESS description file into C++ or Java languages and which also can generate an IDL file or OWL file from an EXPRESS file. System architects, software engineers, information system consultants can use these standards to define their information model for construction industry in standardized way. Construction engineers can test this information model with ease using standard testing tools and testing method, which is also a part of standard architecture of information systems for virtual construction.

Retargetable compiler which generates executable code for a target processor and performance profiler are required to design a processor optimized for a specific application. This paper presents an architecture exploration methodology based on ADL (Architecture Description Language). We synthesized instruction set and optimized processor structure using information extracted from application program. The information of operation sequences executed frequently and register usage are used for processor optimization. Architecture exploration has been performed for JPEG encoder to show the effectiveness of the system. The ASIP designed using the proposed method shows 1.97 times better performance.

The intelligent railway operation information architecture is to provide the railway passengers with the intermodal transportation information service. The purpose of the information architecture is to suggest the information service architecture of the intermodal transportation structurally. First, the architect procedure is to analysis the user requirements and according to these requirements, is to make the description of service requirements. Then secondly, it decides the service items and based of these items, it is to construction of service architecture. Finally, service package provide an accessible, deployment oriented perspective to intelligent railway operation information architecture
